The flames of the council fire leap and crackle, casting a lurid glow on the stern visages of the assembled warriors. Many of these wear brilliantly-coloured tunics of cloth or dressed buckskin, more or less tastefully adorned with beadwork or shining silver plates. Over this, carelessly thrown, or gracefully dangling from its wearer's shoulder, is the outer "robe" of soft buffalo hide, blazoned all over with hieroglyphics and pictures setting forth the owner's feats of arms or prowess in the chase, and among the scalp-locks fringeing tunics and leggings may be descried not a few that originally grew upon Anglo-Saxon heads. But all is in harmony, tasteful, barbarically picturesque; and the air of self-possessed dignity stamped upon the countenances of these plumed and stately warriors could not be surpassed by the most august assembly that ever swayed the affairs of old civilisation. One more personage is there whom we have omitted to mention. Leaning against a lodge pole, as thoroughly unconcerned and at his ease among the red chieftains as ever he was in Belgravian boudoir, his splendid face as impassive as their own, sits Rupert Vipan, and if ever man lived who was thoroughly calculated to inspire respect in the breasts of these warlike savages, assuredly he was that man. That he is here at all is sufficient to show in what honour he is held among his barbarian entertainers. And now in order to render more clearly the drift of the subsequent debate, some slight digression may here be necessary. The Sioux, or Dahcotah, as they prefer to be called, are about the only aboriginal race in North America whose numbers and prowess entitle them to rank as a nation. They are sub-divided into clans or tribes: Ogallalla, Minneconjou, Uncpapa, Brule, and many more, with the specification of which we need not weary the reader, but all more or less independent of each other, and acting under their own chiefs or not, as they choose. At the time of our story the whole of these, numbering about 60,000 souls, occupied a large tract comprising the south-western half of the territory of Dakota, together with the adjacent extensive range in eastern Montana and Wyoming, watered by the Yellowstone and Powder Rivers and their tributaries, and commonly called after the last-named stream. On the border-line of Dakota and Wyoming, and therefore within the Indian reservation, stand the Black Hills, a rugged mountain group rising nearly 8,000 feet above the sea level, an insight into whose wild and romantic fastnesses we have already given.
